cooxrne vnssnn Application filed April 28, 1927, Serial No. 187,272. Renewed November 17, 1928.

This invention relates generally to improvements in cooking vessels, for domestic use, having particular reference to the steamor type of cooker.

An important object of the invention rcsides in the provision of an article of the above-mentioned character wherein novel and unique assemblage of parts, all inter-related, results in the instantaneous conveyance of heat units at relatively high temperature to the material to be cooked.

Another object is to provide an assemblage of parts, as set forth in the foregoing paragraph, which will be adaptable to any container, such as atin pail, or the like, purchasable at any hardware store.

Another object resides in the provision of means in the form of tubes of variable height for permitting the escape of an excess quantity of Water, when expanded, to flow out of certain shorter tubes and thereby not interfering with the discharge of steam through certain longer tubes.

Still another object is to provide means for circulating the turbulent boiling water to a point for re-heating in the event an error is made in adding too much water to the cooker. A still further object of the invention is to provide an article of the above-mentioned character which may be readily and conveniently disassembled for cleaning purposes and which may be constructed at an extremely lesser cost of production, highly eificient in operation and economical in the saving of heat.

lVith these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel' formation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated inthe drawings, and particularly pointed out in the claims,

In said drawings: Figure 1 is a central vertical sectional view of the complete cooker.

Fig. 2 is a plan view thereof with the cover portion removed.

Fig. 3 shows a slightly modified form of closure member. i

Fig. 4 illustrates another slightly modified form of closure member.

sleeve member. I

Referring now more particularly to the ac companying drawings, wherein like characters of reference denote similar parts throughout the several views, the numeral 5 depicts a form of container, having a cover 6 arranged therefor. The particular form or dimensions of said container. are of course'variable depending on its use so long as a compartment 7 is provided in the upper portion thereof for the reception of'vessels containingthe vegetables, meat, or other food-pr0dnets to be cooked. v

The invention proper comprisesthe parts positioned Within the lower portion of said container '5, shown in F ig. 1. Upon inspection of said Fig. 1 it will be observed that I have provided a perforated member or shield 8, open at the bottom and having an inturned flange 9 at the top thereof defining the opening 10, (see Fig. 2). Arranged concentrically within said shield 8 isa sleeve member 11, having a flared bottom portion, as indicated at 12, the bottom rim thereof bcingarranged adjacent the inner periphery ofthe base of said shield 8, while the upper portion of'said sleeve or shell member 11 is constricted to present a somewhat elongated extension 13, terminating below said opening 10. Said flared bottom portion of said shell is provided with a row of apertures 11, as will be pointed out hereinafter. v

The other element of the article, shown in Fig. 1, comprisesa closure 14-, having a circumferential top rim portion 15 fitting into said opening 10 and havin its top surface 1n the same plane w th the top of said 1nlevel by v 21, the serrated bottom of said shield 8 and of closure member is illustrated.

former and terminating below the plane thereof for the purpose clearly announced in the operation of the article hereinafter.

Upon a closer inspection of Fig. 1, it will be noted that the bottom edge of said shield 8 is notched, or serrated, as indicated at 20 and that perforations are both provided in the sides of said shield as well as the inturned In the'operation of the cooks a vessel con- 7 taining the matter to be cooked, is placed above the topsof said tubes 18, as indicated by the dash and dot lines of Fig. 1, depending vertical fillers being adopted to effect the proper spacing if desired. A small quantity of water is placed in said container 5 to the approximate height indicated, which finds its circulating through said apertures the apertures 11? in. said shell member 11, when all parts are assembled as clearly shown in Fig. 1. The container is now placed over a gas stove, or the like, and within an appreciably short period of time the water begins to boil and the steam thus generated passes up through the shell 11 and through the opening in the tubes and thus contacts with the bottom of the cooking vessel thereabove. In view of the superabundance of heat, the food material in' said vessel is rapidly cooked. In the event too much water has been placed in the container the overflow caused by the expansion of said water will circulate through the shorter tubes 19., which terminate below the other tubes 18, as aforesaid. It should also be remembered that boiling water ejected through said .tubes 19 runs out upon the inturned flange 9 of said shield 8 where it maybe returned by means of the perforations 21 in saidflange; and also when only a small amount of water is present in said container the condensation of the steam generated, if any, may be pass through said perforations 21 back to the water level In Fig. 3 of the drawings a modified form This is substantially similar to the form illustrated in Fig. 1 with the exception that the tubes 18 and 19 may be formed integral with the top portion, as by pressing out operations for instance, in order to reduce the number of oints.or seams in said member. Said closur ing the same with a. closed top portion 14*, as shown'in Figs. 4 and 5. This form may be used when it is desired to warm or simmer the contents of a cooking vessel.

' Figures 6 and 7 of the drawings are dinember 14 may be further altered by providrected toward a modified form or forms of shields 8, each having an inturned top flange 22, bent inwardly for a short distance, as indicated at 23 to define the openings 24, between which is frictionally engaged the extension 13 of said sleeve member 11. In both forms apcrtured ears 25 may be provided, which are secured to the parts, as indicated at 26,

excellent place is provided for the convenient removal of the parts from the container. this time it is pointed out that thescope of my invention includes as possibility of acid ing this removing means to the parts shown in Fig. 1. its distinguished from my other form of shield, the part shown in Fig. 6 is without perforations and in view of the opening in the central portion thereof, I prefer to use a perforated plate 27, (see Figs. 8 and the top thereof. Obviously an ini perforated plate may be used for warming or Referring again to the 9), over simmering purpose. 7 form illustrated in Fig. 7, it will be observed that the striking similarity therebetween ceases with the provision of the openings 28, preferably inthe form of notches, purpose noted under the description of my preferred form. I v I In view of the provision of the elongated extension 18 ofsaid member 11, the closure member 1a frictionally engages therewith for V maintaining said parts in assembled. relation.

All or the parts may be lifted en bloc from the bottom of the container 5, if desired, and then separated for cleansing purposes.

lVhile the above presents the preferred forms of the invention, it is to be understood that minor changes and alterations may be made therein without departing' from the spirit of the invention or thescope of the appended claims.

I claim:
